Answer:
<h2>3.14159</h2>
Step-by-step explanation:
A) Pi value using circumferences
C = circumference
d= diameter
Formula: C = Pi*d⇒Pi = C/d
Circle A)
Pi = 21.98/7 = 3.14
Circle B)
Pi = 18.84/6= 3.14
B) Using areas
A = area
r = radio = diameter/2
Formula: A = Pi*(r^2 )⇒ Pi = A/(r^2)
Circle A
Pi = 38.465/(3.5)^2= 3.14
Circle B
Pi= 28.26/(3^2)= 3.14
Answer:
if the pyramid has a square base and to find a volume you have to find the area of the base(length*width) and multiply that with the pyramid's height and then multiply 1/3 to find the pyramid's volume
Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
Y= 0, 21
Answer:-4.2
Step-by-step explanation:(-3,-5)
Equation, y=x+y
Y=.6x+3
-5=.6(-3)+3 then solve
1) Describe the relationship of input and outpunt values for a composite functions.
The composition of the functions f(x) and g(x) is defined as:
(f ° g) (x) = f [g(x) ].
That means that the output of the function g(x) is the input of the function f(x).
2) Is the inverse of a function always a function?
No, the inverse of a function is not always a function.
Remember that a function cannot have two different outputs for one or more input.
The reason is that if the original function has two or more inputs that result in a same output, when you inverse the original function, the outputs of the original are the inputs of the inverse function and the inputs of the original are the outputs of the inverse. That implies that the inverse function would have some inputs related with more than one output, which is the negation of a function.
